Changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this'invention.

IVhat is claimed is- 1. In a device of the class described, the combination of a journal-box having avertical face at its back and provided therein with a ballrace, a series of antifriction -balls mounted in the ball-race, and a bearing-ring arranged over the balls in position to receive the end thrust of an axle, said bearing-ring being capable of vertical and horizontal movement to relieve the journal-box of friction from the end thrust of an axle when passing around a curve, substantially as described.

2. In a device of the class described, the combination of a journal-box provided at its back with a ball-race, a series of antifrictionballs arranged in the race, a bearing-ring covering the balls and provided with a groove to receive the same, said bearing-ring being provided with a peripheral flange, and plates secured to the journal-box at opposite sides of the bearing-ring, conforming to the configuration of the same and engaging the flange thereof, substantially as described.

3. In a device of the class described, the combination with an axle provided with a collar having lugs, of a journal-box, a bearingring mounted on the journal-box at the back thereof and interposed between the same and the collar of the aXle, said bearing-ring being provided with lugs to be engaged by those of the said collar and being capable of rotary, vertical and horizontal movement, and antifriction devices interposed between the bearing-ring and the journal-box, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.

J. DAVIS FULIJEN.
